According to the invention the vaporizer comprises a substance cartridge comprising the at least one vaporizable substance, wherein the vaporizable substance is provided as a substance section on or as a tape, and the substance section is arranged movable in a predefined transport direction in the substance cartridge.

The present invention is directed to a smoking article. In the state ofthe art it is known to use flavor releasing elements, for example to atleast partially limit the smoke taste. Furthermore, consumers appreciatethe taste released by those releasing devices. However, these smokereleasing devices are usually complicated to handle and notconsumer-friendly. Furthermore, those releasing devices are usually notvery versatile as to different flavors. Another problem arising withdevices known from the state of the art is that usually a long heatingup time is required. Also in some cases a high variability in taste andvapour volume arises from puff to puff.

It is therefore an object of the invention to enhance the versatility ofthose smoke releasing devices. This object is reached by the object ofclaim 1. Preferred embodiments of the inventions are object of thesubclaims.

In this embodiment the vaporizer may comprise a seat and/or receptionarea for the substance band.

In a preferred embodiment, the drive is included in the vaporizer andtherefore the drive element is not replaced when a cartridge isreplaced.

In another preferred embodiment the vaporizer comprises a tensioningdevice for the tape.

This tensioning device may be for example an element which controls thedrive to move the tape section. Also tensioning elements comprisingsprings or the like might be used. In another preferred embodiment thevaporizer comprises a guiding means to guide the tape along the heaterand especially along a heating surface of the heater. It is alsopossible that the guiding means and or the tensioning means comprises atleast one and preferably two more rollers between which the tape isguided.

In another preferred embodiment the vaporizer comprises a calculator tocalculate or measure a length of the tape. Also, this calculator maymeasure, how much tape already had been used. Therefore, for example auser may be informed that the tape has to be replaced soon.

In another preferred embodiment the drive is suited to move the tape ina non-continuous manner.

In another preferred embodiment the invention therefore suggestsbobbinized and/or rolled substrates, especially tobacco substrates suchas reconstituted, sheet tobacco (RTB/RTS), cigar binder, and the like,which are preferably impregnated with vaping agents, especially in acartridge.

The above-mentioned heater is preferably an electric driven heater, ithowever would also be possible that the heater is a gas driven heater.

The present invention therefore provides an immediate readiness to use,a very low heating up time, low thermal insulation requirements and alsoa comparatively low temperature of the device shell or housing.

Furthermore, the invention provides a constant puff-by-puff vapingexperience and also a minimized inter-puff variability.

Also, the device allows a daily consumption of for example 100 puffs andno spill, cleaning or refilling procedure. The fast heating up time isespecially reached by the low mass of the material which has to beheated.

In a preferred embodiment, the transporter is suited to transport thetape and/or the specific quantity of fresh material, for example thequantity which is required for one puff into a heating area at themoment of the next puff.

In another preferred embodiment, a diameter of the tape might be in aregion between 2 mm and 30 mm, preferably between 4 mm and 20 mm andmost preferably between 8 mm and 12 mm.

In another preferred embodiment the device provides an area ofevaporation of the material, which is greater than 20 mm², preferablygreater than 30 mm², preferably greater than 40 mm², preferably greaterthan 50 mm², preferably greater than 60 mm², preferably greater than 70mm².

In another preferred embodiment the device provides an area ofevaporation of the material, which is smaller than 500 mm², preferablysmaller than 400 mm², preferably smaller than 200 mm², preferablysmaller than 100 mm².

In another preferred embodiment, the area of evaporation is selectedsuch that per puff a mass of between 5 and 100 mg, preferably 15 to 40mg, more preferably between 20 and 30 mg are in the heating area.Detailed investigations of the applicant have shown that the mentionedquantities are in a good region to on the one hand reach sufficientmaterial for a puff made by the user and on the other hand reach a fastheating of the material by the heating device is reached.

In another preferred embodiment, the heater provides a temperature rangewhich is between 100° C. and 400° C., preferably between 150° C. and350° C. and very preferably between 180° C. and 250° C. In anotherpreferred embodiment the heater allows a heating range, which is greaterthan 100° C./s, preferably greater than 200° C./s and preferably greaterthan 300° C./s. Preferably, a control device is provided, which allowsthe heating only when a puff is made.

In another preferred embodiment the tape and/or the material to beheated is air permeable. This serves especially to enable air flow fromthe mesh through the material.

In a preferred embodiment the tape is porous and/or perforated orespecially pre-perforated. In a preferred embodiment, a porosity level(measured in CU (Coresta Unit)) may be between 50 and 30.000 CU,preferably 1000 to 10000, preferably 2000 to 6000 CU

In another preferred embodiment of the invention after or before eachpuff the consumed matter is transported away from the heating zone and anew matter is transported into the heating zone. So for example in suchan embodiment a cartridge for rolled matter might contain between 2 gand 8 g, which serve for about 100 puffs (as assumed daily consumptionof a user).

In another preferred embodiment the tape is provided as a single layertape or a double layer tape. In another preferred embodiment, the heateris arranged stationary with respect to a housing of the device. In thiscase, the substrate is moved through a fixed heating position. However,it would also be conceivable that the heating position is changed ormoved with respect to a fixed substrate.

In another preferred embodiment a static spot heating is reached duringa puff. A control device controls the drive such that the substratemoves between puffs.

Preferably, the substrate moves across a heating zone. In anotherpreferred embodiment it is also possible that other parts of thecartridge are heated, for example the roller device for heating andtransport can be heated. In another preferred embodiment the heatingdevice is an inductive heating device. In this case magnetic fields areused to produce the heating or to heat the heater.

The advantage of this embodiment is that it is very fast and also a fasttemperature control is possible. In another preferred embodiment thedevice can be handled between temperatures of minus 15° C. and plus 40°C. Also, handling should be possible in case of temperature jumps, forexample when users using the device go from the inside of a heated roomto the outside. Also, as mentioned above a gas heating would bepossible. The heater can be for example an electric heater or a gasheater. Gas heaters might be advantageous for very low temperatures

A permanent heating would be possible but a non-permanent heating isadvantageous for energy conservation. In another preferred embodimentboth a battery or a feed and/or charge capacitor may be used forenergizing the heater.

In a preferred embodiment a set of plurality capacitors is provided. Itis possible to discharge all capacitors in a time between puffs if thistime is long enough to avoid overheating. It is also possible todischarge only a part of those capacitors if the time between puffs isshort. In this case, a flexible response to the required energy isprovided.

In a preferred embodiment the cartridge can have dimensions of about 40mm to 80 mm in the length direction (this base is required for twobobbins of tape material and a heating zone between the two roles).

As mentioned above, the invention suggests also a two-track approach toenable the user to switch between two different taste experiences withinone cartridge.

Preferably, both the vaping agent and flavor are identical. Therefore, aliquid migration can be avoided.

However, those two tracks can be different. Therefore, it is possiblethat the two tracks comprise a different porosity or differentperforation levels for the same substrate.

It would also be possible that the two tracks comprise a different basetobacco substrate (for example paper sheet vs. cast-sheet or darktobacco vs. bright tobacco. Also, combinations of these measures areconceivable.

In another embodiment also a tobacco free material would be possible.For example a porous and/or perforated paper material with sufficienttensile strength could be used as a filter plug wrap (PW) and can beimpregnated with for example PG/G/Flavor. In this case, the generatedvapor does not contain any nicotine or taste originating directly fromtobacco.

The objective of the invention is also reached by a substance cartridgefor vaporizers characterized in that the cartridge comprises the atleast one vaporizable substance, wherein the vaporizable substance isprovided as a substance section on or as a tape, and the vaporizablesubstance is arranged movable in a predefined transport direction in thesubstance cartridge, wherein the vaporizable substance comprises atleast two substance sections which differ from each other in at leastone characteristic feature.

The objective of the invention is also reached by a vaporizer comprisinga mouth piece, the mouth piece being in fluid connection with avaporizing section, wherein the vaporizing section comprises at least afirst vaporizable substance and a heater to heat the vaporizablesubstance. The invention is characterized in that the heater is suitedto heat a vaporizable substance the vaporizable substance being providedas a substance portion on or as a tape.

FIG. 10 another embodiment of a heater according to the invention.

FIG. 1 shows a vaporizer 1 according to the invention. This vaporizer 1comprises a housing 30 inside which elements of the vaporizer asespecially a battery 14 and a control unit 16 are arranged.

Reference numeral 2 refers to a mouthpiece of the device. Inside thismouthpiece 2 an optional filter 22 is arranged. Furthermore themouthpiece may comprise a ventilation 24 which preferably is provided asan adjustable ventilation. Preferably this ventilation can be arrangedin the filter area.

Reference sign V denotes a vaporizing section inside which arevaporization of vaporizable matter takes place. Reference numeral 8denotes a heater which serves to heat the vaporizable substance. Thevaporizable substance is provided in a cartridge which may be insertedin the vaporizer 1. Accordingly the vaporizer 1 and especially thehousing 30 of the vaporizer 1 may comprise a recess into which thecartridge is to be inserted.

The cartridge 10 comprises two bobbins 32, 34, which serve to carry thevaporizable substance 12 which is provided as a tape. The vaporizablesubstance can be unwinded from bobbin 32 and (after use) be winded ontobobbin 34. Reference numerals 36 and 38 refer to guide rollers, whichserve to guide the tape 12 in the region of the heater 8. These guiderollers are preferably also arranged inside the cartridge.

The reference numerals 42 and 44 refer to switches, by which the usercan chose, which section of the tape is to be heated and such by whichthe user can select the sort of vaper the vaporizer is to create.Reference numeral 15 refers to a port of the vaporizer, especially acharging port to charge the device and/or the battery. This port isespecially a Micro USB port.

FIG. 2 shows a vaporizable substance 12 according to a preferredembodiment of the invention. This vaporizable substance is transportedin a transport direction T. The vaporizable substance 12 is provided asa tape having a first substance section 12 a and a second substancesection 12 b. These two sections are provided parallel to each other andextend both in the transport direction. FIG. 2 is a plane view of thetape, and therefore the first and second substance sections 12 a, 12 bare arranged in a width direction of the tape. However, these twosections can be arranged in a thickness direction of the tape in orderto form a layered structure so that one of the layers will be broughtinto contact with the heater and the other layer will be not.

Reference numeral 12 c refers to a parting section which separates thetwo substance sections 12 a and 12 b from each other. Also this partingsection 12 c serves to prevent the two substance sections 12 a, 12 binterfering which each other.

Also the heater 8 can comprise two heating sections (not shown) whichcan be controlled separately and which serve to heat exclusively one orthe other of the two substance sections.

FIG. 3 shows an example of a guide roller 50 according to the invention.As can be seen, this guide roller comprises a body 52 and two (disclike) edges 52 a and 52 b, between which the tape (not shown) can beguided. Therefore, the material will be kept in track. Preferably, thetobacco strip or the tape is homogeneous in structure to ensure that thepath stays true. It is furthermore possible to use a different materialfor the roller to reach a better heat efficiency. Therefore, the heatloss can be limited.

It would also be conceivable that the roller has a shape which deviatesfrom a circular shape, for example a polygonal shape. This would becomparatively easy to realize.

FIG. 4 shows another embodiment of the invention. In this embodiment,the tape 13 is soaked with a soaker device 60. Here it is possible thatthe tape is guided through this soaker to be soaked with material to bevaporized. The heater 8 heats the tape with the material and a puff P ofvapor can be made.

In this case, a liquid application can be made through a center pipe inthe roller. Therefore, for example a technology like in case of a ballpen could be used which touches and applies the medium to be vaporized.

FIG. 5 shows another embodiment of the invention. In this case, acarrier 54 with through holes can be provided, which allow a betterapplication of steam. For better orientation, FIG. 8 also here refers tothe heater. In principle the heating element could also be for example asolid plate such as a solid metal plate. In this case however an airflow would be prevented. Therefore, in one embodiment a “perforated”heating element is suggested, as for example a mesh. With such aperforated heating element an airflow is improved and the vape can bepicked up into the desired airstream more efficiently.

FIG. 6 shows another embodiment of the invention. Here, the tape isguided in a closed loop. The application of the substance can be madewith an applicator 62, which touches the tape between rollers 55.Moreover, the rollers 50 comprise spring elements 51, which improve thetension of the tape when it's guided along the heater 8.

It is noted however, that spring guides 50 can also be used in otherembodiments of the invention. Therefore, this spring tension can be usedalso for one-time use with a pre-impregnation.

FIG. 7 shows another embodiment of the invention. Here, perforatingrollers 84 are provided, which can be used to make perforations in thetape 12. The rollers may comprise small, for example needle-likeprotrusions. In another embodiment, the heater can be provided havingopenings 82, through which the evaporated material can pass. In otherwords, the heater 8 has here a grill design to ensure precise heatingsteps while ensuring the proper air flow.

In a special embodiment, a double grill can be provided for increasedheating from bottom to top. In other words, the heater here comprises aplurality of fingers between which a gaseous medium can pass. Also it ispossible to guide the tape around this heater device and such create akind of back wall with the guide so that the material increases the heatof the flavor in the heating area.

In a preferred embodiment, the heating device can be pressed against thetobacco material to even improve the heating efficiency. For thedifferent rollers, for example a simple plastic pin could be used.However, it would also be possible that a pin together with a ballbearing or a cylinder bearing is used. In this way, the friction couldbe reduced.

FIG. 8 shows another embodiment of a heating device. In this case, aninduction heating device is used. The heater comprises an induction coil94, which serves to heat a metal 92. The tape 12 is guided between theinduction device 94 and the material 92 to be heated.

FIG. 9 shows an embodiment in which the tape 12 is guided along theheater 8. A pressure device could be used to pressure the tape 12against the heater 8.

The heater can here be formed as a “mesh-like” heater. Upon contact theair flows through the “mesh-like” heater 8, takes up vaping substancesfrom the tape 12 and becomes the inhalable vape.

FIG. 10 shows another embodiment of a heater. In this embodiment, aplurality of flow holes is provided in the heater block to ensure an airflow. In a preferred embodiment the holes have a circular shape.Preferably a diameter of the holes is between 0.1 mm and 5.0 mm,preferably between 0.5 mm and 2.0 mm, and more preferably between 0.5 mmand 1.5 mm. For density, the area ratio of holes ranges, irrespective ofthe pattern, between 5% and 90%, preferably between 20% and 70%, andmore preferably between 30% and 50%. For square or rectangular mesh-likeheater, the same ratios apply to meet the same area per hole ranges.Especially, in the case of square mesh, a hole diameter ranging from 0.1mm to 5.0 mm corresponds to an area per hole ranging from 0.1 mm² to 20mm², and hence a length of one side ranging from 0.1 mm to 4.4 mm.

In a preferred embodiment a pressure drop of the heater is higher than20 mmWC (mm water column), preferably higher than 50 mmWC, preferablyhigher than 75 mmWC. In another preferred embodiment the pressure dropof the heater is lower than 200 mmWC, preferably lower than 125 mmWC,preferably lower than 100 mmWC.
